INHERITANCE OF GRAIN PROTEIN CONTENT IN CROSSES OF THREE HIGH-PROTEIN WHEATS (TRITICUM AESTIVUM L.)
Abstract
Introduction of new methods in agriculture and new strains of crops, particularly wheat, rice, and maize, has resulted in spectac- ular grain yield increases in underdeveloped countries. However, little attention has been given to the nutritional improvement of crop species by genetic means. Emphasis on yield is important. Man's minimal caloric needs must be satisfied before nutritional inadequacies of his diet can be dealt with effectively. Nutritional improvement of crop species must, therefore, be accomplished without yield reductions.Genetic control of grain protein quantity in maize has been known since the classic high and low selection experiments conducted at the Illinois Agriculture Experiment Station beginning in 1898 (8). The first report of a wheat significant genetic increases in grain protein content was by Middleton, Bode and Bayles (20). He reported that Atlas 66 had the ability to lay down more protein in its grain than did other soft wheat cultivars, without a reduction in grain yield. Johnson, Schmidt, and Mattern (17), reported the results of a 3-year study involving 15 Atlas 66 x Comanche F2-derived families which had been selected for high grain protein content. Average pro- tein superiority of some of the families was more than 3% actual protein.
